CAN-FILLING MACHINE. v

Original application filed May 18, 1920, Serial No. 382,368. Divided and thia'application filed October 8,

i 1921. seriarno. 506,299.

To all whom it may concern:

Be it'known that I, CHARLES H. AYARS, a citizen of the United States, and resident of the city of Salem, county of Salem, and State of New Jersey, have invented certain new and useful Improvements in Can-Filling Machines, of which the following is a specification.

My invention relates to improvements in can filling machines, the present application being a division of my prior application filed May 18, 1920, Serial N 0. 382,368.

One object of my. inventionis to provide a can filling machine of a durable and coinparatively simple construction which can be run at a high rate of speed and which will be operative to accurately deliver predetermined quantities of, vegetables or the like, such as peas, into cans and also to deliver a predetermined quantity of brine or liquor into said cans.-

Another object is to so construct my im-' proved machine that the means of delivery will be such asto cause practically no splashing of the liquor as it enters the cans and for this reason it is unnecessary to provide any sealing means between the tops of the cans and the guiding means for the articles and liquor.

Another object is to so construct the parts of my improved machine that there will be practically no waste of the liquor due to leakage.

A still further object is to provide means of simple construction and which can be easily and quickly the quantity of the to enter the cans.

Another object is to so arrange the parts that they can be easily put together, lubricated or attended to by an operator.

A still further object is to so construct and arrange the parts that they can be operated by the application of a comparatively small operated to vary either articles or liquor desired amount of power.

A further object is to provide means which will guard against injury to the articles so as to prevent crushing or disfiguring the articles during the operation of the parts.

These objects, and other advantageous ondswhich will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which,

Referring to the drawings, 21 represents a frame or supporting structure which includes a top section 22 having :1 depending flange 23 and an aperture 2" through which depends a flange 24 of a partition or bed plate 25. The bed plate is secured to the top section 22 in any suitable manner and as illustrated, bolts 27 are provided for this purpose. A vertical shaft 26 is rotatably mounted in a bearing 21 secured to the frame 21; said shaft having a rotatable movement but preferably no vertical movement. The bottom of the shaft 26 has a bevel gear 28 thereon which meshes with a bevel gear 29 on a transversely extending drive shaft 30. The upper portion of the shaft 26 extends through a hole in the bed plate as clearly shown in Figures 2 and 3. i

A measuring wheel 31 is positioned above the bed plate 25 andincludes atop section 32 and a bottom section 33'. The bottom section 33 is keyed to the shaft 26 as shown at 34 and rotates upon the upper surface of the bed plate 25. The top section 32 has a'central hollow boss 35 having its opening extending upwardly from the bottom and in which the top portion of the shaft 26 freely fits. An adjusting screw 36 fits a tapped opening 37 in the boss and the lower end of the adjusting screw is adapted to engage the top end of the shaft 26. Thus the top section 32 of the measuring wheel is supported freely on the top of the shaft 26 and may be moved-upwardly and downwardly by the turning of the adjusting screw 36 as is obvious from the showing in Figures 2 and 3. The top section 32 of the measuring wheel has a number of depending sleeves 38 which are open at their bottom: said openings extending to the top of the section 32 so that passageways are provided from the top to the bottom. In the present instance, the top section 32 is provided with five of. these openings as clearly shown in, Figures 10 and 11. The sleeves 38 are arranged annularly and slidably or telescopically lit within respective holes 39 in the bottom section 33 of the measuring wheel.

A top or hopper plate 40 has a central hole 41 through which the boss 35 extends so that the hopper plate 40 rests upon the top of the section 32 of the measuring wheel 31. -It will be noted thatin view of. the fact that the shaft 26 is keyed to the bottom section 33 of the measuring wheel 31, the measuring wheel will be rotated by the shaft 26. In order to prevent the rotation of the hopper plate 40, said hopper plate has a lug 42 which extends into a vertical groove 43 in a standard 44; said standard being secured to the partition or bed plate 25 as clearly shown in Figures 1, 3, 1t) and 20. Thus the hopper plate 40 is free to move upwardly and downwardly due to the adjustment by means of the adjusting screw 36 but: rotation of said hopper plate is prevented. The, hopper plate 40 has a hole 43 which is surrounded by a flange 44; said hole extending entirely through the thickness of the hopper plate. A hopper 45 has its lower end fitted within the cans with the peas as is usually the custom.

A distributing wheel 46, as clearly shown in Figures 2, 3, 5, 13, *14, 15 and 16 is positioned below the bed plate 25 and has a central hole 47 through which the shaft 26 extends. A key 48 rotatably secures the distributing wheel 46 to the shaft 26 and a collar 49 is positioned under the distributing wheel and prevents movement of the distributing wheel in a vertical direction. The upper portion of the'peripheral edge of the distributing wheel 46 is flanged at 50 so as to surround the lower part of the flange 24 as clearly shown in Figure 3. The formation of the distributing wheel 46forms an important feature of my present invention and the same will now be specifically described.

A number of chutes 51 are arranged annularly and extend entirely through the distributing wheel 46 in respective alignment with the holes 39 of the lower section of the measuring wheel 31. The outer portion or shell 52 of the wheel 46 tapers downwardly and an annular partition 53 separates the chutes 51 from the shell 52. Radial partitions 54 separate the chutes 51 at their tops; the construction being such that the tops of the chutes 51 are in the form of sectors of a circle such as shown in Figure 15. These chutes 51 taper downwardly between the radial partitions 54, the annular partitions 53 and the central. solid portion 55 of the wheel as clearly shown in Figures. 15 and 16; said chutes 51 at their bottoms being substantially circular. The radial partitions 54 extend outwardly beyond the annular partition 53 and join the outer frusto-conical part 52 so as to provide pockets 56 which are respectively in radial alignment with the chutes 51. The, chutes 56 also taper downwardly and at their bottoms communicate with the extreme lower portions of the chutes 51 through the medium of passages 57. These passages 57 are made extremely narrow for the purpose of slowly permitting liquor, which is, discharged into the pockets 56, to run into the cans which are positioned below the bottoms of the chutes 51 as will hereinafter be more fully described. The. cans 58 are fed by any suitable mechanism upon a disk 59 distributing wheel 46.

which is positioned below the bottom of the present instance, is fixed and a wheel 60 is mounted above the disk and keyed to the shaft 26. The cans 58 are fed between the spokes 61 of the wheel 69 in positions di-- rectly under the respective lower portionsof the apertures 51.

A. discharge port 62 is formed entirely through the thickness of the bed plate 25 at a position remote from the opening 43 be low the hopper and a hole 63 is also formed in said plate in radial alignment with a portion of the port 62. The port 62, as clearly shown in Figure 8, is of an elongated character' taken in a direction concentric with the axis of the shaft 26; the length of said discharge port preferably being greater than thewidth of any one of the chutes 51 at its to for a purpose hereinafter described. he port 63 is preferably located opposite ornearly opposite the end of the elongated port 62 which is last reached in the normal rotation of the distributing wheel.

A liquid or liquor tank 64 has a part 65 of its bottom extending at an incline; the upper portion of the inclined part projecting above the bed plate 25 at one side of the measuring Wheel 31 as clearly shown in Figures 1 and 2. A plate 66 within the tank is secured to the inclined part 65, to project above the level of liquor in said tank, and has a stuffing box 67 projecting out of an opening 68 in said inclined part 65. An inclined shaft 69 extends through said stufling box into the tank and has a bevel gear 70 secured thereto which meshes with another bevel gear 71 on the shaft 26. The lower end of the shaft 69 is rotably supported in the bearing 21. The upper surface of the plate 66 is preferably ground or otherwise smoothly finished so as to be practically fiat and a disk 71, which is keyed to the shaft 69,-has its lower surface in rotatable contact with the fixed plate 66. The disk 71 has a number of holes 72 cut entirely therethrough and in these holes are fitted tubes 73. The tubes 73' are open at their tops and bottoms and are arranged annularly and adapted during ro tation toldip into the body of liquor within the tank 64 and become filled with the liquor at a position below the level 74 and then, during the rotation of the shaft 69 and disk 71*, to move to a position above the level 74 of the liquor into register with a hole 75 in the plate 66 and a hole.76 in the bottom 64 of the tank. A pipe or nipple 77 connects the hole 76 of the tank 64 with the hole 63 of the bed plate 25; said latter hole being lower than the hole 76. Thus during This disk, in the this means the capacity flow downwardly through the pipe 77 and hole 63 into any of the pockets 56 which happens to be below the hole 63 so that the liquor will be discharged successively into' the pockets 56 as the latter, during the rotation of the distributing wheel 46, pass below the hole'63. -.It will be noted that the measuring wheel 31, distributing wheel 46 and can actuating wheel 60 operate as a unit during the rotation of the shaft 26 and the shaft 69 is so geared to the'shaft 26 that a measured quantity of liquor will be deposited in each of the pockets 56 as the latter pass under the hole 63.

As a means for varyin the quantity of liquor entering the tubes, provide the following mechanism: A ring 78, as clearly shown in Figures 1 and 2, is connected to a central hub 79 by arms or spokes 80. Displacement. plugs 81 are secured to the ring 78 and depend into the upper ends of the tubes 7 3. The hub 79 is hollow and the upper end of the shaft 69 is slidably keyed within the lower end of the hub. An adjusting screw 82 fits a tapped hole 83 in the top of the hub and the inner end of this screw abuts the top of the shaft 69 as clearly shown in Figure 2, By turning the screw 82, the displacement plugs 81 canbe moved into or out of the tubes 73 and by of the tubes can be varied to suit different requirements such for example as when it is desired to vary the amount of liquor to be put in the cans.

The tank 64 can be secured in any suitable manner to the frame 21 in addition to the connection formed by the pipe 77 and I have illustrated braces 84 which connect with the tank and frame as shown in Figure 2. The sides of the tank 64 are made sufficiently high that should any leakage occur between the uppermost portions of the disk 71 and plate 66, the leaking liquor will flow downwardly back again into the tank. Therefore, even though irregularities occur by wear between the disk 71 and plate 66, there will be no waste of material and if the operator finds that an insuflicient amount of liquor is being supplied to the cans, due to leakage as above described, he can compensate very quickly for the amount of liquor lost by leakageby turning the adjusting screw 82 to withdraw the displacement plugs 81 part way out of the tubes, 73; thereby giving the tubes 73 a greater initial capacity so that even though a part of the liquor returns to the tank by leakage there will still be sufficient liquor in the tubes and the cans will receive their proper allotment.

In order to guard against mashing or otherwise disfiguring the peas, due to the relative rotation between the hopper plate 4 '40 and the top section of the measuring wheel, I form a curved groove 85 in the bottom surface of the hopper plate 40 as clearly shown in Figures 2, 4 and 6; said groove extending from the opening 413 to a position above the discharge port 62; the extent of the length of the groove 85 being clearly shown in Figure 4. It is obvious that the peas within the hopper 45 will drop into 10 the spaces provided by the sleeves 38 and holes 39 of the measuring wheel as the sleeves successively pass under the opening- 43. Thus the space provided by said sleeves and apertures will be filled. with the peas and during the rotation of the shaft 26, any of the peas which are part way within the opening 43 and sleeves 38 instead of being mashed or cut will pass uninjured through the space provided by the groove 85 until thesleeves and corresponding openings reach the discharge port 62. The peas will then fall through the discharge port and the chute 51 in the distributing wheel which is immediately below the discharge port and after passing through the chute 51, the peas will fall into the can 58. Then a measured amount ofth'e liquor will be discharged into the adjacent radial pocket 56 but owing to the small restricted passage 57 leading out ofthe pocket, the liquor will flow slowly.

into the can, without splashing, during the H-continued rotation of the elements which are connected to the shaft 26. By making "thefupper portions of the pockets 56 comparatively wide .in their directions concentric'tothe axls of rotation, the liquor can "be discharged into said pockets without fear of splashing or leakage and after the liquor has once been; deposited in the pockets, it

so 'will continue to fiow slowly into the can during the continued rotation of the elements and owing to this manner of discharging the liquor into the cans, I have found in actual practice that it is not necessary for is any seal betwcen'the tops of the cans and the bottom of the distributing wheel. Further than this, the flow of liquor into the cans is so gradual that it will not disturb thepeas in the cans to such an extent as to throw the peas out of the cans as often occurs in many. can filling machines made prior to my present invention.

As shown in Figure 8, the arrangement of parts is such that a measured unit of .15 granular material reaches the elongated port 62 before the corresponding measured unit of liquid reaches its port 63. Inasmuch as the discharge of the granular material is practically unrestricted and the liquid port 60 is positioned adjacent that end of the elongated port 62 toward which the can is traveling, all, or substantially all of the granular unit will drop into the can before the liquid pocket begins to fill. Owing to the 66 fact that the outlet from the liquid pocket is restricted the major portion of the liquid will be retained in'the pocket until the can has passed the granular port and be discharged gradually as the travel of the can is continuous.

The capacity ofthe'measuring spaces provided by the measuring wheel can be easily and quickly varied merely by turning the adjusting screw 36 to cause the sleeves 38 to move into or out of the holes 39. A guide rail 86 for the cans has an arcuate portion 87 which forms an inclosure for the cans and as shown in Figure 9, the cans may enter between the spokes of the wheel 60 in any suitable manner and are ejected or moved 5 ofli the disk by means of the arms and a divisional rail 88. The cans after being moved ofl the disk may be deposited on any suitable conveying means such for example as the rotatable table 89 which is shown in dot-an'd-dash lines in Figure 1. Thus the cans are maintained in positions respectively under the chutes 51 and are slid upon the disk 59 by the spokes 61 of the wheel 60 and take a circular path concentric to the shaft 26 so as to be in a position to receive the peas and liquor in accordance with the above description;

hile- I have described my invention as taking a. particular form, it will be understood that the various parts of my'invention may be changed without departing from the spirit thereof. and hence I do not limit myself to the precise construction set forth, but consider that I am atliberty to make 100 such changes and alterations as fairly come within the scope of the appended claims.
